Abstract :

Experimental Modal Analysis (shortened as EMA) is a method to predict the behavior of a system by effectively using the modal or viation data. It helps in understanding and evaluating the dynamic behavior of a system in actual scenario. In this paper, an attempt is made to study the free viation analysis of the cantilevered beams of different materials and lengths using the EMA technique. EMA is implemented using the OROS FFT analyzer and NV Gate software to acquire the viation data of the specimens. The results obtained by experimentation are cross checked using the ANSYS simulation package
